London: A young couple of Indian origin have devised a multi-functional jacket that can carry everything from an iPad to a small blanket.

Ideal for a traveler, the project has raised $3 million by crowd-funding so far.

A seasoned traveler, 29-year-old Chicago-based Hiral Sanghavi was fed up of long flights as he was unable to carry all of his essentials.

He, along with his wife Yoganshi Shah, created “the Baubax jacket” that has a neck pillow, hood, eye mask, gloves and drink holder among many other features, the Daily Mail reported on Tuesday.

The jacket, also known as “Swiss Army jacket”, has 15 pockets and will be available for $109 from November.

The multiple compartments can store tablets, phones, earphones, chargers and a small blanket. Sunglasses are protected in a pocket that includes a micro-fiber cloth for keeping them clean.

“We wanted to offer creative lifestyle products with a variety of different designs for men and women, so we have created jackets, blazers and even bomber jackets,” Hiral, who is completing an MBA at the Kellogg School of Management in Illinois, was quoted as saying.

The detachable neck pillow can be inflated in two seconds using a built-in valve and deflated with one pat. The pillow is suitable for different sleeping positions, and is kept in the hood where the eye mask also slides out.

The jacket also flaunts a zipper that doubles up as a pen and a touch screen stylus.

Other useful touches include the drink pocket that is made with an insulated neoprene material to keep beverages hot or cold.

It also comes with a passport-sized pocket for easy access to travel documents while boarding and going through airline security.

Indian astronomers have found an active galaxy in a very bright state with 10 times more X-ray emission than normal

Indian astronomers have found an active galaxy in a very bright state with 10 times more X-ray emission than normal, equivalent to more than 10 trillion of the sun, and located five billion light years away that could help probe how particles behave under intense gravity and acceleration to the speed of light.

It could help study the role of strong gravity and acceleration of matter in the formation, interaction and evolution of galaxies in the early universe.

Every galaxy in the universe is believed to host a supermassive black hole at its centre. In some galaxies, the black hole is actively devouring a large amount of material and shooting a jet of plasma almost at the speed of light towards us. These are called blazars.

OJ 287 belongs to a class of blazars known as BL Lacertae objects which show very rapid and large amplitude flux variations but barely discernible emission line features.

This class of sources emit in the whole electromagnetic spectrum, a rather uncommon phenomenon which requires extreme physical conditions. Hence, a study of such sources tells us about the behaviour of matter in an extreme gravitational field where it is difficult for light to escape from the vicinity of the black hole.

Astronomers at Aryabhatta Research Institute of Observational Sciences, an autonomous institute of the Department of Science and Technology, Government of India, have been monitoring one such black hole system named 'OJ 287' since 2015. This source shows a repeated optical brightness enhancement almost every 12 years.

"The repeated optical enhancement makes OJ 287 very intriguing as this class of sources does not show any repeating features in flux variations. The repeated optical enhancement made the researchers believe that the system hosts a binary black hole," said a release from the Ministry of Science and Technology.

In 2020, the source was very bright at optical and X-ray bands with X-ray flux more than 10 times the normal (non-active phase) flux. This flare was very different as it was not expected in models proposed for this source and thus, indicated a more complex system and physical conditions.

Investigating the extreme brightness shown by OJ 287 at optical and X-ray bands, astronomers led by Pankaj Kushwaha and Alok C. Gupta reported the source in a completely new spectral state.

The team argued that this change of state holds clues to the researcher's quest to understand how matter behaves in very strong gravity and how it accelerates the particle to almost the speed of light -- a feat that is out of the scope of even the most advanced CERN accelerator.

The research published in 'The Astrophysical Journal' tracked the details of changes in optical to the X-ray emission spectrum of the source with time from 2017 to 2020 -- after the second brightest X-ray flare of the source. It revealed how the source gradually started to change its spectral behaviour from mid-2018 to the new spectral state in 2020.

The study included data recorded by the ground-based facility operated by Physical Research Laboratory, Ahmedabad, operated Mount Abu observing facility in near infra-red bands and the space-based NASA's satellites -- the Niels Gherel Swift satellite at optical, UV and X-rays with gamma ray data from the Fermi satellite, the release added.

Tospread awareness about the significance of reading, Rachna Kalra, who hails from Gurugram (Haryana), started the Silent Book Club in the year 2019.

Who doesn't like reading, and that, too, reading along the company of mother nature? Well, this book club is truly a fantasy turned to reality.

As said by a regular reader at the Silent Book Club, “There is something meditative about reading. Sitting quietly with a book, without any distractions, is almost spiritual for me," this exactly is the case with many such readers.
